Mike and friends
I have been using the standard setup with 2 RRCs for months now, with success. Additionally, I have Com2 connected to the radio with a straight serial cable, and I can control the radio with either DX4WIN or Win-Test.
Now I decided to add a RRC-Micro PC to use on the road. I've just installed it, and I can get the SIP connected, the buffer bar moves, but there is no sound at all.
When I start HRD, I configure the Com port to the virtual pair of Com2, the software connects but when it comes to read the radio frequency, it fails.
I read somewhere in this forum that I might need to tie pins 7 and 8 at the radio port in order to get it working. Is that the case? If so, why does my cable works with the standard configuration + Win-Test and not with the Micro-PC + HRD?
